If ur just starting out then i dont think you need the amp and the speakers,,,just use a regular stereo system
eveyone has one of those
and u wont need the head fones wen u just starting out
so save up and get good headfones, they are really important

using ur regular stereo system while u are starting out can save u alot of money,,,arent u happy i suggested that?

oh and NEVER turn up ur music,,if ur gona be a dj
its like driving really slowly if you are a race car driver
its no good

and never listen to one thing for too long,,take breaks
keep those in mind and u will keep good ears
